OperationPI versions

The AX-CNDR-XXX controls room heating andcooling. The unit provides a 0-10V heating and / orcooling output relative to the setpoint / setback /deadband and proportional band. ( On/off heating onCR3 version) If the integral time is set the output willalso vary with temperature error over time. The fanspeed can be set in 3 or 10 steps in manual or when autois set the fan speed is automatically controlled in 3 or10 steps relative to the 0-10V heating and coolingoutput. (10 steps only available on 0-10V fan speedversions)



On/off versions

The AX-CNDR-XXX controls room heating andcooling. The unit provides On/off heating and / orcooling output relative to the setpoint / setback /hysteresis. The fan speed can be set in 3 steps in manualor when auto is set the fan speed is automaticallycontrolled in 3 steps relative to the Fan band setting.

Key card contact / occupancy input

This accepts a volt free output from a keycard oroccupancy sensor (or similar device). When the inputis closed the room will be considered occupied (thePerson symbol is displayed in the House symbol). Ifthis input is enabled in the menu the heating and coolingwill be set back by the setback value and the fan set tolow speed when the room has been un-occupied for theexit delay time. A count down of the exit delay isdisplayed. If this input is connected to a PIR (forexample) and the exit delay is set the PIR’s internaldelay should be set to zero. If the key card actions arenot required they can be disabled and the input used asa digital input.

AX-CNDR-HCF / AX-CNDR-HCFBN

Unit operates as standard AX-CNDR-HCE/BN unitexcept the analogue fan output is preset to drive anAX-CNDR-RMAF 3 fan interlocked relay module.

AX-CNDR-HC / AX-CNDR-HCBN

Unit operates as standard AX-CNDR-HCE/BN unitwithout any fan controls or output.

AX-CNDR-HCP / AX-CNDR-HCPBN

Unit operates as standard AX-CNDR-HCE/BN exceptthe fan output is 5V, 100Hz PWM, 10mS cycle time.

AX-CNDR-AP / AX-CNDR-APBN

Unit operates as AX-CNDR-HCE/BN but it has twoidentical 5V, 100Hz PWM 10mS cycle time fan outputsand only 1 0-10V heating or cooling output.

Window contact input

This accepts a volt free contact from a window switch.The switch should be closed when the window is closed.If the window input is enabled in the menu and thewindow is open the heating and cooling output is set tozero and the fan is set to speed low (UUin is displayed).If the window contact actions are not required they canbe disabled and the input used as a digital input.

User controlsOn / Off

The user can switch the unit on or off. When the unit isoff the cooling output will be zero and the fan is off. On/ Off switch actions can be disabled via the operatingmenu.

Setpoint

The user can adjust the setpoint between the Setpointhigh and Setpoint low limits set in the menu. Fortimeclock versions the setpoint will only change for theremainder of the current time period reverting back tothe preset value during the next cycle. Setpoint switchactions can be disabled via the operating menu.

Fan speed

0-10V fan speed version

The user can set the fan speed in 3 or 10 steps as selectedor auto. When auto is selected the fan speed will be setin 3 or 10 steps relative to the 0-10V heating or coolingoutput. The fan speed is displayed in three or ten stepson the bottom display bar. To provide more control andreduce noise each 3 step high/med/low fanspeed outputcan be set individually or a 3 point output profile canbe set for 10 step operation.

3 relay fan speed version

The user can set the fan speed to low/med/high or auto.When auto is selected the fan speed will be set relativeto the 0-10V heating or cooling output for PI versionsor relative to the Fan band for On/off versions. The fanspeed is displayed in three steps on the bottom displaybar.

Fan speed switch actions can be disabled via theoperating menu.

Fitting and removing front plate

To fit front plate with the back plate fitted to the wallcarefully bring front plate towards back plate and locateswitches in front plate holes then move plate to one sideand clip over one side of back plate then push front platein opposite direction and push front to clip onto backplate.

To remove front plate carefully insert slottedscrewdriver into slot on side of thermostat and leverforward making sure plate does not fall.



Fan output voltage profile

Using the menu the three points FANSPEED LOW/MEDIUM / HIGH are set. A value of 45% equates to4.5V etc. When three step mode is selected these threepoints set the LOW / MEDIUM / HIGH voltage outputs.When in 10 step mode these three settings are used toplot the output voltage profile at steps of 3.3 6.6 and 10as shown on the graph below. This is then used tocalculate the output voltages for steps 1 to 10.

Network connections ((BN versions)

It is not recommended to connect more then 32 deviceson a single network. This number is dependent on localwiring and conditions, ie cable lengths, interference etc.

It recommends to use twisted pair cables specificallydesigned for RS-485 networks to reduce anyinterference. All devices should be connected NET+ toNET+ and NET- to NET-. A NETCOMMON terminalis provided and if required all the units on the networkshould be connected to the same NETCOMMON whichshould be grounded at one point. The devices shouldideally be connected in a single chain with no stubs.

On board termination resistors are provided and onlythe devices at each end of the chain should have theirresistors connected, place TERM jumper in EL position.All other devices should be set to the none EL position.It is also recommended that a fail safe voltage is appliedat one point on the network, usually at the maincontroller or router.



Timeclock (T version)

The time clock operates on either a 5/2 day cycle or a7 day cycle. Each part of the cycle has 2 on / off timesettings, 1 On / 1 Off and 2 On / 2 Off. The unit has 2timeclock setpoints, SP1 is used during 1 On / 1 Offperiods and SP2 is used during 2 On / 2 Off periods. Ifthe setpoint is adjusted during a timer period the in usevalue will change for the remainder of that period butit will not be stored and will revert back to SP 1 or SP2 for the next cycle.

If 1 On / 1 Off and 2 On / 2 Off periods overlap SP2 haspriority. This allows 1 On / 1 Off to be set for the wholeday and 2 On / 2 Off to be set for a time within the day.

ModePress On/Off button to cycle through the modes, On /Auto / Off. When auto mode is selected the time displayshows Auto for 5 seconds followed by the time. Thetime display will then continue to change between timeand Auto to show the unit is in Auto mode.
